Patent number: 8035546Abstract: A method for the detection of at least one moving object in a pre-determined detection zone by way of a speed sensor. The method includes the following steps: determining a detection zone within an illumination region of the speed sensor; detecting a speed signal, particularly a Doppler signal, at least with the entry of a moving object into the illumination region; estimating an entry of the moving object into the detection zone on the basis of a speed of the object, and of a distance between a boundary of the illumination region and the detection zone.Type: GrantFiled: July 10, 2007Date of Patent: October 11, 2011Assignee: Siemens AktiengesellschaftInventors: Martin Nalezinski, Claus Seisenberger

Patent number: 7990313Abstract: An FMCW radar has a variable frequency microwave signal source for outputting a microwave signal, a frequency divider, a phase-locked loop, a loop filter and a reference signal source. The frequency divider is connected between the output of the variable frequency microwave signal source and an input of the phase-locked loop. The loop filter is connected between the output of the phase-locked loop and the input of the variable frequency microwave signal source. The reference signal source is connected to an additional input of the phase-locked loop. The frequency divider is adjustable, in particular digitally adjustable. A method for operating an FMWC radar includes adjusting a variable frequency microwave signal source by way of a closed-loop control circuit which uses a reference signal of a reference signal source, especially of a quartz oscillator, as the reference value, and a frequency-divided output signal of the microwave signal source as the feedback value.Type: GrantFiled: July 10, 2007Date of Patent: August 2, 2011Assignee: Siemens AktiengesellschaftInventors: Martin Nalezinski, Claus Seisenberger

Patent number: 7283087Abstract: A radar is provided with transmitting means for transmitting a signal and with receiving means for receiving a reflection of the transmitted signal. The inventive radar is characterized in that the transmitting means is provided with a transmitting oscillator and the receiving means is provided with an evaluation oscillator. The transmitting oscillator is excited by the evaluation oscillator and/or the evaluation oscillator is excited by the transmitting oscillator in a quasi-phase coherent manner.Type: GrantFiled: February 16, 2004Date of Patent: October 16, 2007Assignee: Siemens AktiengesellschaftInventors: Martin Nalezinski, Martin Vossiek

Patent number: 7242259Abstract: The invention relates to a device, especially an active backscatter transponder, for generating an oscillator signal based on a base signal. It comprises an oscillator for actively constructing the oscillator signal by oscillations, an input for the base signal and an output for the oscillator signal produced. The oscillator can be induced by the base signal to generate oscillator signal in a quasi-coherent manner to the base signal. For the transmission of data, the device further has a data insertion device for inserting data or a data signal into the oscillator signal. A corresponding suitable receiver receives and processes the received signal that was generated and transmitted by such a device as a quasi-coherent signal. A separation device removes the signal portions of the oscillator from the received signal via the base signal of a receiver-side oscillator, with a data retrieval device for retrieving the inserted data.Type: GrantFiled: February 24, 2003Date of Patent: July 10, 2007Assignee: Symeo GmbHInventors: Patric Heide, Martin Nalezinski, Claus Seisenberger, Martin Vossiek

Patent number: 7119736Abstract: Separation determination systems for determining the separation between a base station and a transponder, whereby the base station includes an oscillating signal source, for generating a signal and a transmission device for broadcasting the signal. The transponder includes a receiving device, for receiving the signal from the base station, an oscillator, for generating a signal which is phase-coherent therewith and a transmission device for broadcasting the phase-coherent signal. The base station furthermore includes a receiver device, for receiving the phase-coherent signal from the transponder and a separation determination device for determining the distance between base station and transponder. The system and components may be improved whereby the oscillator in the transponder is energized with the received signal in order to generate a quasi-phase-coherent signal.Type: GrantFiled: November 5, 2002Date of Patent: October 10, 2006Assignee: Siemens AktiengesellschaftInventors: Patric Heide, Martin Nalezinski, Martin Vossiek, Leif Wiebking

Patent number: 6317075Abstract: An FMCW sensor in which a transmission signal is generated from a high frequency of a fixed frequency oscillator and a modulated, low frequency of a second oscillator. The modulated frequency is processed in a delay line with a surface wave component to form a reference signal. A transmission mixer with a hybrid coupler having a 90° phase difference and terminated by diodes is employed in a transmission/reception means. A measured signal from the transmission mixer together with the reference signal is interpreted in an evaluation means.Type: GrantFiled: February 25, 2000Date of Patent: November 13, 2001Assignee: Siemens AktiengesselschaftInventors: Patric Heide, Martin Nalezinski

Patent number: 6181273Abstract: Microwave radar: an additional modulation of the microwave signal (s (t)) provided for the emission or of the reception signal (e (t)) makes it possible to separate the payload signal from the noise signal parts in a following demodulation and filter unit (HP, MI2, TP). To this end, a modulation unit (MO, RG) for suitably modulating the signal to be emitted is provided preceding the antenna (A). The undesired noise signals produced by the components of the radar sensor itself are not modulated and can therefore be separated from the payload signal by filtering. This separation ensues after a raw measured signal (mess' (t)) has been generated by mixing transmission and reception signal (MI). A renewed demodulation with the modulation signal (r t)) of the modulation unit supplies the final measured signal (mess2 (t)) determinant for the determination of the distance, whereby the noise signals are previously removed by high-pass filtering and/or are subsequently removed by low-pass filtering.Type: GrantFiled: July 12, 1999Date of Patent: January 30, 2001Assignee: Siemens AktiengesellschaftInventors: Patric Heide, Martin Nalezinski
